I left a toxic friendship and his girlfriend wants me to talk it out with him and be friends again, I refuse, am I the asshole?

I was apart of a discord server that I was very much involved and connected in. I became friends with this guy in the server and overtime he became more and more abusive and manipulative towards me. This negatively impacted my mental health and caused me to self harm several times. I decided with a heavy heart that I had to leave the server.
Since leaving the server and cutting off all contact with him, I have been thriving. I made my own server and envited my friends and it's been great.

However his girlfriend, who also owns the server I left, is upset. When I left I explained to her that I had to separate myself from certain people otherwise I wasn't going to make it. Yesterday she told me I should talk it out with her boyfriend and that the friendship could still be saved. I said no and she said that she was tired of all the petty drama.

Am I the asshole?
